SAMUEL SHOEMAKER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE PENN-SYLVANIA STEEL RAILWAY TIE COMPANY, OF PHILADELPHIA, PENNSYLVANIA,

A CORPORATION OF DELAWARE.

METALLIC RAILWAY-TIE.

Patented Feb. 18, 1913.

Original application filed December 30, 1911, Serial No. 668,730.Divided and this application led January 27, 1912. Serial No. 673,808.

To all whom t may concern:

Be it known that I, SAMUEL SHOEMAKER, a citizen of the United States,residing in the city and County of Philadelphia, State of Pennsylvania,have invented a new and use ful Metallic Railway rI`ie, of which thefollowing is a specification.

My invention consists of a metallic railway tie in which one surface issubstantially plane and uninterrupted and the other side has hollowchairs secured to it, and this application is a division of my patentapplication, Serial No. 668,730, filed December 30, 1911, for metallicrailway tie.

It further consists of such a tie in which longitudinal creeping of thetie is prevented.

It further consists of provision for perfect anchorage of such a tie.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

The annexed drawings and the following description set forth in detailone mechanical form embodying the invention, such detail constructionbeing but one of various mechanical forms in which the principle of theinvention may be used.

In said annexed drawings-Figure 1 represents a perspective view of myimproved metallic railway tie. Fig. 2 represents a longitudinal sectionof the tie. Fig. 3 represents a transverse section on the line in Fig.2. Fig. l represents a plan view of a portion of Fig. 2.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to said drawings, the reference numeral 1 indicates arectangular sheetmetal plate, which constitutes the body of the tie.Said body-plate has flanges, 2, upon its side-edges and flanges, 3, uponits endedges. Rectangular chairs, 4l, formed with open sides anddiverging end-flanges, 5, having foot-flanges, 6, are secured,preferably by rivets, 7 upon the under side of the bodyplate, near theends of the same. Said chairs may be east, forged, pressed out ofsheetmetal, or formed in any desired or convenient manner, and theirbody-portions, 8, are preferably concave and longitudinally corrugated.Tongues, 9, are struck out of the body-plate to form opposed abutmentswhich bear against the edges of the foot-flanges of the chairs toprevent longitudinal movement of the latter. Tongues, 10, are struck outof the body-plate at diagonally opposite sides of the rail-seats of thetie to bear against the foot-flanges of the rails, and openings, 11, areformed adjacent to said tongues and serve for the insertion ofscrew-bolts or other fastenings for the rails. The chairs may have a.iilling, 12, of semi-plastic or partly yielding material, to cushion therails, deaden no-ise and exclude moisture and ballast from entering thechairs.

The tie is simple and inexpensive of manufacture and forms a levelroad-bed. The side and end-ianges of the body-plate afford a hold uponthe ballast, and cause the chairs, being sunk in the ballast, not onlyto brace those portions of the tie upon which the load of the rails andpassing train falls, but to prevent longitudinal and transverse movementor creeping of the tie. The concavity and corrugation of the under sideof the body-portions of the chairs give the latter a firm grip in theballast.

Other modes of applying the principle of my invention may be employedfor the mode herein explained. Change may therefore be made as regardsthe mechanism thus disclosed, provided the principles of constructionset forth, respectively, in the following claims are employed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A metallic railway tie, comprising a body-plate having flanged edges,and a chair having a concave and corrugated body-portion and divergingend-flanges formed with foot-flanges secured to the face of thebodyplate.

2. A metallic railway tie, comprising a body-plate having iianged edgesand tongues struck out to forni opposed abutments, and
